A family business in second generation

Esa Tuominen founded Steel Master Finland Ltd in 1995. The company started as a steel structure manufacturer, but soon expanded its services to the construction of skid mounted units. As the demand for the units grew, the company outgrew its facilities and decided to move into larger premises in Mynämäki in 1999 where it has expanded ever since. In 2015, the business was passed on to the next generation as Esa’s sons Markus, Matias and Tuomas took over the company.

Modern, functional workshops

Steel Master workshops are located in South-Western Finland with easy access to main roads and harbours. The production facilities totalling to 4000 m2 are designed for efficient and troublefree production. The lifting capacity of 20 tons enables also manufacturing of large entities.
